SPECIFICATION forming part of Letters Patent No. 508,028, dated November'7, 1893.

Application nea March 2. 1893.

vin which similar figures and letters of reference indicatecorresponding parts in all the views.

lFigure 1 is a'plan view of the cultivator. Fig. 2 is a longitudinalvertical section taken practically on the line 2-2 of Fig. 1. Fig. 3 isa front elevation of the cultivator, the pole being shown in section,the section being taken on the line 3-3 of Fig. 1; and Fig. 4is atransverse vertical section taken practically on the line 4-4 of Fig. 1.

In carrying out the invention the frame of themachine may be said toconsist of two beams A and B, forward arches 10 and 1l, rear arches 12and 13, front and rear guide plates 14 and 15, receiving the crownorbody of the arches, and a socket 16, carried by the rear plate andadapted to receive the rear end of the tongue or pole V17. The beams Aand B, are arranged opposite each other; they are horizontally located,andthey are made to converge at their forward ends and diverge at theirrear ends. As each beam is of like construction, and furthermore, aseach beam carries disk oultivators in the same manner, the detaileddescription will be conined to one of them. Each beam consists of twoparallel and spaced bars 18 and 19, the extremities of both of the barsbeing placed atan angle to the body, the bodyof the beams occupying adiagonal positionwith respect to the extremities, the extremities beingmade straight; and the forward extremities are designated as a, whilethe rear extremities are designated as a. The bars 18 and 19, areconnected near the forward and rear ends of their body portions by meansof cross bars sena No. 464,379. (No model.)

20, which cross bars are` provided with an outwardly extending centraleye 2l. A boxing C, is located at the rear of the beam and a boxing C',is located at the front thereof. The rear boxing consists of a casing,comprising as is shown in Fig. 4, a body portion 22, which is hollow andprovided ateach side with a recess 23, and an upper socket 24, locatedtransversely upon the body and a lower transverse socket 25, togetherwith a rear socket 26, shown best in Figs. 1 and 2, which socket 26, isprovided with a circular interior, while the remaining sockets, andlikewise the interior of the body are made more or less rectangular. Theeye 21 of the rear cross bar 20 of the beam is made longer than theinterior of the body of the boxing C at the front thereof, and ispivotally held therein through the medium of a pin 27; and the rear endportions a of the bars ofthe beams are made to enter the side recesses23 in the body. Thus the beam may have more or less play in the boxing.

The forward boxing C', is identical with that shown and described withreference to the rear boxing C, with the exception that its outer orfront socket, which is the equivalent of the rear socket 26 of the rearboxing, has a rectangular or polygonal interior and is designated as26a; and the forward end of the beam is connected with the forwardboxing in like manner as the rear end is attached to the rearboxing.`Each beam is provided with a series of slides D, which are adapted to bemoved longitudinally uponrthe side barsof the beam, or the body portionthereof. The construction of a slide is best shown in Fig. 4, in whichit will be observed thatthe slide consists of an upperl bar 29, a lowerbar 30, and an upright bar 3l connecting the upper and lower bars backof the inner ends of the latter, the outer end portions of the upper andlower bars being connected by stand. ards 32, which standards extendsomewhat above the Vupper bar andare provided with bearings, thestandards being placed at suitable intervals apart and being connectedat their outer ends. In the standards of each slide a worm 33, isjournaled, and as shown in Fig. 1, one end of the worm is squared toreceive a wrench, as illustrated at 3 4 in the said figure. One side barof a beam passes between the upper and lower bars 29 and 30 of a socket,and in engagement with the inner upright bar 31, while the other andouter side bar of the beam passes through openin gs 35, produced in thestandards; and after the slides have been properly adjusted upon thebeams they are held in their adjusted' position by set screws 36, whichare passed up throughthe connecting bars ofthe slide standards to anengagement with the outer bar of the beam,as is likewise best shown inFig.4; but any equivalent of the said fastening device Inay be employedif in practice it is found desirable.

It will be observed that by reason of the peculiar construction of theslides a central open space 37, is obtained; and each standard isadapted to receive a shank 38 of a cultivator, and said shank which ispreferably round, is carried upward through the slide,

being loosely mountedtherein; and through this central space 37 theupper end l of the i shank extendsa suitable distance above the iuppenface oftheI slide. Each shankislpractieally angular or Lshaped,rasis clearly sl1own\inI`ig.-4, the vertical member-being1u mounted in aslide, While the horizontal mein'- ber extends inwardly beneath the beamand is adaptedto carry a disk cultivator'E. The

shank ofa disk cultivator is adapted for vertical adjustment in itsslide, and likewise is adapted to be turned readily therenso as to`cause the disk `cultivatorto entertlle ground -to a greater or lessdegree, and in order to give itany desired inclination beneath the beam.Thevertical adjustment is provided for by placing a collar 39 upon thevertical member of the shank within the opening 37 of its slide,.thecollar being providedwith a` suit- `able set screw. Thus by loweringtheset screw the shank may be raised or loweredf and by tighteningit theshank `may `be held in 4au adjusted position, and as the collar islocated within the slide and loosely placed therein the shank may beturned Without the collar oiering any resistance.

A rotary movement is imparted to the cul` tivator shank by securing uponthe upper endiofthe shank a mutilated or segmental gear 40, which ispreferably secured thereon by means of a set screw, as shown in Figrl,

and this `gear meshes `with the Worm carried by the slide in whichtheshankis` located. Therefore, it will be observed that by manipnlatingthe worm 33 the shank may be turned in whatever direction it is desiredto place the disk E, which fit carries.

The cultivator disk E, is of peculiar con-i mounted loosely upon thehorizontal member of a cultivator shank; and the cultivator is held uponthe shank either by means ot a nut, as shown in the drawings, or byscrewing a cap on the hub over the end of the shank, in which latterevent all dust or dirt is excluded from the axle of the cultivator.

Any desired number of cultivators may be placed upon a beam, and thebeams are connected at the front by the arches 10 and 11 and at the rearby the arches 12 and 13. The arches at the front and rear are arrangedone above the other. The arch 12, which is the upper arch, has itsmembers carried downward and outward in opposite directions and thencehorizontally into the upper socket 24 of the rear boxing C, while themembers of the `lower arch 13, are carried in the same dircction andmade to euterthe `lower sockets 25 of the rear boxings. Each archisimade in two sections, asshown in Fig.` 4, one section being connectedwith the rearboxingof each beam, while the upper ends of the arch`sections are made toenter sockets produced in the upper and lowerportions of-the guide platesl; the said sockets `,being ldesiguated inthe drawingsas 15. Therefore, when two beams have been coupledtogetheriby the rear arches the space between Ithem may be enlarged or`lessened by adjustingthe arch sections in their sockets;` and aftertheadjustmenthas been made the arch sectionsare held firmly in theirsockets by means-0t set screws 43, or the equivalent thereof,` asshownin Fig. 3.

The front portions of the beams-A and B, are connected in like manner asthe rearportions by meansof the front arches'lO and 11, whicharesimilarly disposed to the rear arches, the sockets in the front guideplate `14, how ever, being designated in the drawings as 14"'. The guideplates are `connected by brace rods 44, which are Apassedfrom plate toplate, en tering said plates betweenitheir upper and lower sockets, theguide rods being provided with suitable lock and check nuts. Ordinarilytwo guide rods are employed, one being located at each side of thecenter of the plate.

The sockets of the frontand rear plates face each other, as shown inFig. 2 g andiupon the front plate at its centeri ears 45, are located,and between said earsf the pole or tongue 17 of the machine ispivoted,while the `rear or butt end of the pole or: tongue is-made to enter thebox or socket 16, secured to lthe centraiportionfof the rear archguideplate 15 uponthe forward face of` saidplate; and as shownparticularly in Figs. 2 and 4, this box, which is open at its front,extends some dis tance `upward beyond the said plate 15; there fore, thetongue 17 hasifree and guided movement inthe box 16, which is of a widthjust sufficient tofreely admit the tongue or pole; and whenlthe machineis drawn over undu latingfor rough ground the rear end ofthe pole willascend or descend, moving freely in IOO its box 16, and therefore therewill be no unnecessary strain upon the team, the machine accommodatingitself to the inequalities of the ground while the pole or tongue willaccommodate itself to the motion of the team. It is necessary, however,in turning corners and on some occasions, to hold the tongue or pole ina rigid position, and this is preferably accomplished by mounting uponthe top of the box 16 a lever 46, and connecting that lever with thepole or tongue near its rear end by an arched link 47,-whereby when thelever is pressed downward and rearward until the link has passed itscenter, the pole or tongue will be locked firmly in the box, and it maybe as conveniently released by throw` ing the lever v46 upward.

The machine is supported upon two rear wheels 48, and these wheelsareimounted upon crank axles 49,each. axle being'independent; and eachcrank axle' is journaled in the rear socket 26 of the rear boxing C. Thebeams, therefore, may be raised or lowered by the manipulation of theseaxles, and this is accomplished through' the medium of levers 49, whicharesecured preferably to the inner ends of the axles, the said leversbeing provided with thumb latches 50, adapted to enter Vracks 5l,secured in any suitable or approved manner upon the rear boxings, asshown in both Figs. 1 and 4. The forward sockets 26a ofthe forwardboxings C', are adapted for use when two or more of the cultivators areto be f coupled together to work in gangs, as it is rying them, and theangle or inclination may be readily changed by operating the worms 33.It -will be understood that the-worms maybe placed upon the inner sideofthe frame instead of the outer side, if'found more desirable.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent;- i
